摘要:

发展了一种分子内芳基噻蒽盐亲核取代环化反应, 通过C—O键与C—S键的选择性断裂, 实现了芳基噻蒽盐的新化学转化, 高效合成了23例高共轭的三苯并九元硫醚化合物. 该反应官能团兼容性优良、 产物收率高且无需过渡金属参与, 为在催化反应中应用广泛的冠醚的合成提供了一种新途径.

关键词: 芳基噻蒽盐, C—S键断裂, 苯并硫醚

Abstract:

Here reported is an intramolecular nucleophilic substitution reaction of aryl-thianthrenium salts, which conducts the selective cleavage of C—O and C—S chemical bonds and represents a novel conversion of aryl-thianthreniums, rapidly assembling the highly conjugated tribenzo-thioester compounds. This developed methodology is charactered by excellent functional group tolerance, good productivities, and metal-free trait. This conversion delivers 23 examples of structurally innovative nine-membered thioethers, which puts forward an alternative synthesizing route for the widely used crown ethers.

Key words: Arylthianthreniums, C—S bond cleavage, Benzo-thioester
